In clinical practice, the primary goal of cardiovascular nursing is to ensure adequate perfusion—the delivery of oxygenated blood to the body's tissues. To achieve this, nurses must master the ability to "recognize cues," a process that involves gathering data through a systematic assessment of the patient's history, physical state, psychological well-being, and laboratory results. Understanding these cues allows for early detection of cardiovascular disease (CVD) and timely intervention.
Risk Factors and Medical History
The first step in recognizing cues is understanding a patient's risk profile. Cardiovascular risk factors are generally categorized into two groups:
- Nonmodifiable Risk Factors: These are factors that cannot be changed, such as age, gender, and family history/genetic predisposition.
- Modifiable Risk Factors: These are behaviors or conditions that can be managed or altered to reduce risk, including smoking, nutrition, and lifestyle choices.
Clinical Note: Cigarette smoking is a major modifiable risk factor that significantly increases the risk for both coronary artery disease (CAD) and peripheral vascular disease (PVD).
When conducting a medical history, the nurse should look for a pattern of previous treatments for CVD, current drug history, social history, and functional history (how the patient's health affects their daily activities).
Physical and Psychosocial Assessment
A comprehensive physical assessment provides immediate, objective cues regarding the patient's hemodynamic status.
Physical Assessment Cues
Nurses use four primary techniques—inspection, palpation, percussion, and auscultation—to evaluate the cardiovascular system:
